This application is a division of my application Number 458,212, filed May 31', 1930, for flier constructions. I

It is an object of this invention to provide an improved wooden flier block having a freely movable gripping member disposed therein and retained in position by a self mushrooming bushing member.

l It is also an object of this invention to provide such an improved flier block in which the self mushrooming bushing is adapted for locking engagement with the flier block.

These and other desirable objects and ad- Yvantages of the present invention will be described in the accompanying specification and illustrated in the drawing, certain preferred embodiments being shown by way of illustration only, for, since the underlying principles may be embodied in other specific mechanical devices, without departing from the spirit and scope of the present invention, it is not intended to be limited to the forms here shown except as such limitations are clearly imposed by the appended claims.

In the drawing like numerals refer to similar parts throughout the several views of which Fig. 1 is an elevation of a bobbin mounted on a spindle and having a flier block and cap together with an associated flier wire held in position by a flier cap;

Fig. 2 is an elevation of a novel flier cap showing means for retaining a plurality of iier wires;

i Fig. 3 is a view similar to Fig. 2 showing means for retaining a single flier wire;

Fig. 4 is a vertical section of a wooden iiier block having a centrally disposed spring for engagement with the spindle, the locking bushing being shown ready for assembling, and

Fig. 5 is a view similar to Fig. 4 showing the locking bushing in position.

Referring now to the drawing there is shown in Fig. 1 a bobbin, l, mounted on a spindle, 20. The latter is `tapered and at its upper portion is adapted to receive a flier block 30, having flier wire 23 mounted therein and held in position by means of an improved flier cap, 11.

In the modification which is .the subject of the present application, the usual bobbin 1 is mounted on a spindle 20 of tapering cross section adapted to engage a wooden flier block 21. This latter is provided withfthe usual groove 22 for receiving thenflier wire 23. The flier wire has depending arms 24 `and thread engaging eyelets 25 as well as the usual central portion engaging the slot 22 in the iiier block. A flier cap 11 configured to the shape of the block, is fitted over the block' and the wires sprung into engagement with the slots 12 and/or 13. As above noted, a plurality of iiier wires may be madeuse of, where desired, by the simple 'expedient of using the pair of double slots 12, rather than the pair of single slots 13. For easy manufacturing and to avoid duplication ofparts, the ltwo series of slots 12 and 13 may be formed in a single device, eitherl set being used at will by the operator. c

The novel flier cap andblock assembly of the present invention is characterized by einl tremely low cost of manufacture, due to the fact that'the wooden blocks mayreadil'y be formed by automatic'machinery and the flier caps may be stamped' or pressedl out from sheet metal of suitable thickness.v

Referring now to Figs. 4 andl 5, there is shown a novel wooden block construction, which is adapted for use with the novel Hier cap of my application No. 458,212, filed May 31, 1930, for flier constructions, of which the present application is a division, thus obviating the necessity of using mill nuts or other such locking devices. The construction shown comprises the usual wooden flier block having the central groove 31 and central aperture 32. A'bushing 33 of 'metal orf other suitable material is forced into the block and 90 engages the wood thereof permanently soy as to serve as a retaining iange for the spring member 34, the latter, it wi l be appreciated, l being adapted to engage a spindle member; and permit the block to freely rotate there# about. A bushing havingl the usual central aperture of a diameter corresponding t0 that of member 33 is provided with a flange 36 of relatively square cross section and ani associated depending flange 37 which'is pro- 100 vided with an outwardly tapering section. The member 35 is adapted to fit into a seat 38 in the block 30 and be compressed or forced into position, against said seat, the section 37 5 mushrooming and digging into the body of member 30, as indicated at 39, thus locking member 35 firmly into place and retaining spring 34 in position. It will thus be seen that the central aperture block 30 together with the bushings 33 and 35 serve to retain the spring 34 in position and rotate freely thereabout. The device just described is particularly adapted for use with-the improved iiier 4 cap of the present invention, and permits the use of cheap wooden construction in preference to a machined metal flier blocky construction.

A iiier cap llhaving a plurality of apertures 12 and 13 oppositely disposed with rezspect to each other at the one edge thereof,

and a central aperture adapted for engagement withy the hub is slipped over the flier block. In operation, the flierV block is inserted in the bushing of the bobbin and the f assembly is then placed over and on a spindle. A flier wire having a central portion adapted to engage channel 31 and abutting thereagainst as a bearing surface is inserted in position, the flier cap is next lowered into posi- 3G. tion over the hub of the block. The arms of the ier wire are bent away from the central portion thereof which is in abutment against the block, until the said arms engage the slots 12 and/or 13 of the said caps, being held in 35B position thereby, and'serving to tense the flier wires in place.

It will now be appreciated that there has been provided a plurality of flier block constructions in which a unitary flier cap of'sheet 4G? metal or other like construction and of suitable size and configuration is adapted to be used and thus permit the use of replaceable flier Wires without requiring dismounting or removal of the flierL blocks from-theirrespec 452tive spindles.

VIn accordance with the provisions of the' patent statutes, I have described the principles of operation of my invention, together with the device which I now consider to rep- Bresent a preferred embodiment thereof; but I desire Lto have it understood that the device' shown is only illustrative of the basic concept of the present invention, and that the said' invention may be carried out by other means.

What is claimed is:

l. A flier including an apertured body poradapted to grip a spindle, a fixed bushing in the body adapted to support the spring and a mushroom bushing oppositeto said lirst bushing and forced into said body.

3'. A bushing for insertion into compressible flier bodies, comprising an annulus having a plurality of peripheral ridges, at least one of said ridges having a cutting edge.

4. A bushing for insertion into compresv'sible flier bodies, comprising an annulus hav-
